Embodiment
Below described example relate to and use the present invention to start personal computer and relate to a kind of personal computer that configuration is used for the non-volatile reprogrammable memory of this computing machine of effectively start that has.Yet the present invention also can be applicable to other and needs the digital processing device of load operation system in order to using, for example, and computer game machine, business PC and telecommunication apparatus.
With reference to Fig. 1, for example understand computer system starting and start process process flow diagram according to the present invention.
Carrying out " cold " with reference to the described method supposition of Fig. 1 starts or " firmly " startup.Skilled person in the described technical field will recognize that described method is suitable equally under " heat " startup or " soft " startup situation.
With reference to Fig. 1, for example, user's activation system power knob in step 1.This is that power supply is applied to this system, and under normal conditions, bios software can the initialization start-up routine.Therefore in step 2, BIOS is activated, and finishes its common power-on self-test (POST) initialize routine, is in following two things then.BIOS or: a) search the booting operating system load module of system disk driver, as what in existing start-up routine, take place; Perhaps: b) selectively, described BIOS is provided by the non-volatile reprogrammable memory that provides in computer system.Even BIOS at first searches the booting operating system load module of hard disk drive, described Boot loader still guidance system from non-volatile reprogrammable memory downloaded stored mirror image, just as following further described, although this may be with good conditionsi, need the user to input to be stored in the password among the BIOS.
Non-volatile reprogrammable memory is provided as integrated circuit, and its addressable computer system for example is provided at it on personal computer motherboard.Perhaps, it is provided as the interior plug-in card of PCI to upgrade an existing machine.Also can otherwise provide non-volatile reprogrammable memory,, make startup method of the present invention be worth doing thereby the system that makes can read its content fully apace as long as satisfy the needs of access system.
Forward step 3 now to, so the booting operating system load module begins start-up course, perhaps directly from the content of non-volatile reprogrammable memory or from the system disk driver.
The non-volatile reprogrammable memory device comprises the memory image of RAM content, and when being loaded into system storage, it is enough to make computer system to be in the spendable state of user, promptly starts computer system.
According to user's needs, the memory image that captures in non-volatile reprogrammable memory and provide can have various ways.For example, non-volatile reprogrammable memory can comprise the memory image of guiding back system working memory (being RAM) content.
For example, another selection is a loading non-volatile reprogrammable storer, and it has the preferred compressed memory image of all data among the current RAM of being stored in.In a preferred form, store this compressed memory image after the shutdown programm formerly, this shutdown programm is similar to the State S4 shutdown programm in the present ACPI 2.0a standard.This comprises the computing machine of computer system and/or the setting of operating system, wherein, described computer system is in the state that uses in order to the user, and preferably offers the use of a user with recovery system, when this system is under the situation identical or roughly the same when beginning to shut down with the user.
The ACPI S4 shutdown details of standard can be from present ACPI standard, finds in the correction 2.0 (http://www.acpi.info).
Memory image also can be the part mirror image of system storage.Therefore, for example, described mirror image can comprise the data that relate to most of operating systems, and being used for constructing or setting up the necessary remaining information of system working memory can be loaded into the working storage from another memory storage devices such as system disk.Under the situation that the size of non-volatile reprogrammable memory will be restricted, for example owing to the constraint of cost, this configuration is preferably, but the present invention still is worth doing, because compare, finish the still significantly minimizing of All Time that start-up course spends with the start-up course of knowing.
Memory image can be initially created in the process of operating system foundation, and perhaps no matter whenever the user carries out great change to computer configuration, and memory image all can be replaced.In addition, when each user began a shutdown programm, memory image also can be caught in.With reference to Fig. 2 these options are carried out more deep discussion.
Preferably, this memory image is compressed, the memory image (CMI) with a compression is stored in the described non-volatile reprogrammable memory like this, and can give for change again from non-volatile reprogrammable in needs.Compression can be saved a large amount of storage space, and decompression procedure does not significantly increase by the present invention the resulting start-up time that has reduced.May use the compression algorithm that obtains such as in open-source Zlib compression storehouse.
Except compression, can also carry out and the same Standard Encryption of hard disk drive memory image, to stop attempt recovering information from storer, when the hard disk drive that carries same data is protected.
Among Fig. 1, when determining to have the memory image of a compression, the user is by prompting input password ((step 9) after step 7) and the input, the CMI that is arranged in non-volatile reprogrammable can be decompressed, and described computer system setting is loaded among the RAM with whole memory contents (step 18) from the CMI that decompresses.If the password (step 8) then land failure (step 10) and computer shutdown (step 13), the simultaneously memory image (step 12) compressed of deletion selectively of a mistake is provided.If deleted CMI, start next time will be a normal start-up routine (step 4-6,23-24).
In case password is by checking, whether the operating system inspection has carried out big change to hardware configuration, and (step 14) normally starts (step 23-24) if big change (step 16) is arranged then carry out.Suppose and do not change start by main assembly (the step 15) application program will be from RAM (step 19) loading service and device driver.Check extra underlying hardware then,, then its mark is preserved configuration subsequently with prompting if any one has problem.Start-up course is faster finished at this point.
Because memory content is loaded into the RAM from non-volatile reprogrammable memory very apace, rather than from system disk searching and transmission, so significantly reduced the required time of start-up course.
Use Microsoft Windows to start one
TMThe PC of operating system is an example, and BIOS at first checks the log-on message in the non-volatile reprogrammable memory, and with windows boot files and kernel loads in storer.Can create registration table if the space allows and it is stored in the non-volatile reprogrammable memory, or with its establishment and be stored in the local hard drive, just as existing system.When loading Windows, device driver will be loaded among the RAM from non-volatile reprogrammable memory.Service and third party start application program will be pre-loaded from local hard drive.A typical personal computer can carry out physically modifying and realize this process by the non-volatile reprogrammable memory chip more than 64,000,000 or 64 megabyte that append on the machine mainboard is provided.Utilization is to the internal support of flash memory file system (FFS) and flash translation layer (FTL) (FTL), and the BIOS that revises on the PC starts from non-volatile reprogrammable memory with permission.MicrosoftWindows
TM, for example Windows XP can be revised by inner drive (being FAT16/32, NTFS and FFS/FTL) or third party's driver and be supported FFS/FTL.Can provide hardware supported by product based on outside plug type PCI.Windows boot files and device driver are added in the non-volatile reprogrammable memory, and third party's start-up routine by physics move to hard disk drive begin the place.
Use in the example of Windows operating system at another, BIOS starts from non-volatile reprogrammable memory, and loads the reconciliation compressed memory image in RAM.Memory image in RAM after, small environment change all can hard disk drive begin the place is loaded and is created.Comprise below (but being not limited to this):
Application program is installed
Non-key startup application program
Registration table
Pagefile (virtual memory)
The physics that the typical PC of an operation Microsoft Windows operating system is made change to above-mentioned example in the content that relates to similar substantially, yet, in the Windows start-up course, create a user, the Windows memory image of described customization 128 megabyte (until 1GB) compression, and be stored in the non-volatile reprogrammable memory.Further customization setting is stored in the place that begins of hard disk drive.
Fig. 2 represents the replacement program of those computing machines, and described computing machine uses BIOS to check that assembly changes.Unique difference of program is that ZBIOS has carried out the operating system that hardware configuration inspection rather than use provide inspection among this program and Fig. 1.
Forward Fig. 3 now to, for example understand a shutdown process according to computer system of the present invention with figure.Described process is from step 26, the shutdown command of user's selection operation system.Operating system is checked the change sign in the step 27 then, as the part of shutdown process.No matter whenever described computer configuration has been carried out great change, described operating system puts 1 with described change sign.A great change can comprise that (being not limited thereto) is following:
(a) new application program is installed
(i) in case os starting, application program is installed just needs charging assembly.
(b) change of registration table
(c) device driver upgrading
(d) services package/patch is installed
(e) service is revised
(f) user environment customization
(i) desktop
(ii) wallpaper
(iii) theme
(iv) sound
(v) icon
(vi) color scheme
So any one new user conversation after starting all is changed to vacation with modified logo.So, when great change took place, for example above-mentioned listed change was changed to described sign very so.The tabulation of the above-mentioned great change that provides is used for clearly illustrating, and non exhaustive.And the user may wish to get rid of some behavior from the above-mentioned table that provides.
Turn back to Fig. 3, if the change sign is depicted as vacation as step 28, operating system is closed the file that all are opened so, equipment and service, but do not preserve any system configuration data, because shown in step 29, in this scope, do not do any change.Operating system continues normal shutdown process then, promptly in the step 30, is implemented as State S5 shutdown at present in ACPI 2.0a standard.Then, computing machine is in certain state, perhaps shuts down voluntarily in step 31 or prompting user closing machine.
If shown in step 32 among Fig. 3 change be masked as true, so with " known the last time is correct " (LKG) compressed memory image be archived to a suitable memory storage, the local hard drive of system for example.This can occur in the step 33.
Then, in step 34, be used for the CMI of last start-up system, promptly effective CMI is used as LKG CMI.
Then, the shutdown programm that operating system initialization has been changed is shown in step 35.
In step 36, use suitable compression algorithm will be stored in all data among the RAM at present and compress and be loaded in the non-volatile reprogrammable memory, become new effective CMI.The memory image of any needs is encrypted and can be carried out in this stage.Then, with reference to as above step 15 is described, operating system is finished the shutdown process of described modification.
According to method shown among Fig. 3, can recognize that the file of the compressed memory image that is used for start-up system is retained.Therefore, be unwanted great change if the user has carried out harmful to machine operation, if perhaps system crash, the user will always have the memory image of a compression, can be used to restart machine.
Turn to Fig. 4 now, according to the present invention, basic processing unit in the example computer system and memory module are as shown in the figure.For the skilled person in the technical field that the present invention relates to, the layout of other of memory device and communication path also are possible.There is a CPU (central processing unit) (CPU) 401 in described system, and a control module 402 is provided therein.Working storage as the form of random-access memory (ram) is provided, non-volatile reprogrammable memory 404 equally also is provided.Data bus 405 allows to realize data exchange mutually between RAM403 and CPU401 via address date control bus 406 under control module 402 controls.Similarly, data bus 407 allows to realize data exchange mutually between non-volatile reprogrammable memory 403 and CPU via address date control bus 408 under control module 402 controls.Therefore, bus 407 allows to include that information is sent in the non-volatile reprogrammable memory 404 among the RAM of whole memory contents.Bus 405 and 407 can be formed system bus.And perhaps the content of RAM403 is compressed, and the compressional mirror picture can transmit to be stored in the non-volatile reprogrammable memory 404 via bus 407 whereby.So, when needs, the memory image that is stored in non-volatile reprogrammable memory 404 can directly send RAM403 to, perhaps at first is compressed then and installs in RAM403.
The advantage of non-volatile reprogrammable memory 404 is that it is a non-volatile stable state equipment in essence, so when stopping the computer system power source supply, the content of non-volatile reprogrammable memory still keeps.Yet skilled person in the art will appreciate that non-volatile reprogrammable memory mentioned in the presents comprises the use of flash memory ram, i.e. the form of non-volatile reprogrammable memory, and it need keep memory contents such as the external power source of battery.
According to the present invention, for example, non-volatile reprogrammable memory device can provide as integrated circuit on system board, perhaps on independent plate or card.Specifically, if desired, non-volatile reprogrammable memory can be provided on the card, for example is the card of SmartMedia or CormpactFlash with reference to those trade marks.
At present some available non-volatile reprogrammable memory product has than hardware driver load time magnitude faster, so, can recognize that method according to the present invention compares with previous technological system with system, great advantage was provided aspect start-up time.
